For the cave phenomena sometimes referred to as a blowhole, see Breathing cave. Blowhole. In geology, a blowhole or marine geyser is formed as sea caves grow landward and upward into vertical shafts and expose themselves toward the surface, which can result in hydraulic compression of seawater that is released through a port from the top of the blowhole.
Haleakalā (/ ˌ h ɑː l i ˌ ɑː k ə ˈ l ɑː /; Hawaiian: Hawaiian pronunciation: [ˈhɐlɛˈjɐkəˈlaː]), or the East Maui Volcano, is a massive, active shield volcano that forms more than 75% of the Hawaiian Island of Maui. The western 25% of the island is formed by another volcano, Mauna Kahalawai, also referred to as the West Maui ...
The Maui Hazard Zone numbers are a different scale from the island of Hawaiʻi's map. The lava flow hazard zones on Maui use a different scale. They can be compared to Hawai'i Island's lava zones. [4] [5] Maui Zone 1 - Includes the crater of Haleakalā and some rift zones, mainly areas that have experienced major eruptions in the last 1500 years.
The Puʻu Kukui Preserve is the largest private nature preserve in the State of Hawaii, dedicated to protecting the watershed lands of the West Maui Mountains. Established in 1988, the 8,661-acre (35.05 km 2 ) preserve has been managed since 1994 by Maui Land & Pineapple Company in participation with The Nature Conservancy and the State Natural ...
Halemaʻumaʻu (six syllables: HAH-leh-MAH-oo-MAH-oo) is a pit crater within the much larger Kīlauea Caldera at the summit of Kīlauea volcano on island of Hawaiʻi. The roughly circular crater was 770 meters (2,530 ft) x 900 m (2,950 ft) before collapses that roughly doubled the size of the crater after May 3, 2018. [ 1 ]
The four younger volcanoes are Lāna‘i, West Maui, Kaho‘olawe, and Haleakalā, which probably formed between 1.5 and 2 million years ago. [2] At its prime 1.2 million years ago, Maui Nui was 14,600 square kilometres (5,600 sq mi), 50% larger than today's Hawaiʻi Island.
The lava can overflow the fissure and form ʻaʻā or pāhoehoe style of flows. When such an eruption from a central cone is protracted, it can form lightly sloped shield volcanoes, for example Mauna Loa or Skjaldbreiður in Iceland. Geologists can predict where new eruptions will take place by tracking the earthquakes that precede the ...
Nakalele Point is a land mass on the eastern edge of the northern tip of the island of Maui in the state of Hawaiʻi. In Hawaiian, Nakalele or Nā-kālele means "the leaning". The Point is known for its blowhole and has become notable for its dangerous conditions when waves crash in. The point and blowhole are located just east of Poelua Bay. [1]
